SAFE OR VAULT DOOR.

Application filed September 11, 1923. Serial No. 662,049.

This invention relates to safes and vaults, and more particularlyrelates to safe. or vault doors, and especially to doors which areuseful for emergency entrance.

The provision of emergency doors in safes and vaults is becoming morepopular, due to the fact that there is an increased desire for meanswhereby access may be had to a safe or vault in case of emergency.Emergency entrances are also desirable and useful for purposes ofventilation. it is desirable that an emergency door he burglar-proof,and yet be readily responsive in the hands of an authorized person, andat the same time be reasonably inexpensive to construct and install in asafe or vault.

The principal object of our invention is to provide a safe or vault doorwhich is burglar-proof, yet readily operable by an authorized person,and at the same time is comparatively inexpensive to construct and toinstall in a vault or safe.

A further object of our invention is to provide a door of the'abovecharacter which is especially suitable for use as an emergency entranceto the safe or vault.

A further object of our invention is to provide novel and improvedlocking mechanism for the door.

Other objects of this invention will be in part obvious and in partpointed out hereinafter. 1

In accordance with our invention, we provide a circular door, preferablycarrying lock mechanism including combination and time features, thedoor being provided with a circular bolt-frame adapted to cooperate witha revolvable locking ring mounted on the vestibule, which ring, inaccordance with its position, locks and unlocks the door, and means areprovided which are operable from the exterior of the door for moving therevolving locking ring on the vestibule into and out of lockingposition.

l-leretofore, the standard type of emergency doors requires squareframes or vestibules. Such frames involve more expensive constructionthan do circular frames. Moreover, in such constructions, the accessiblemeans for operating the bolt-work mechanism has been located on thevestibule jamb. In our construction, such means are located on the door,thus eliminating the expense of locating these means in the vestibulejamb.

In order that a clearer understanding of our invention may be had,attention is hereby directed to the accompanying drawings, forming apart of this application and illust-rating one possible embodiment of;our invention.

Referring to the drawings Fig. 1 is a plan view of a door embodying ourinvention, showing a portion of the vestibule jamb with the doorunlocked;

Fig. 2 is a sectional view of a part of the door and vestibule jamb, andis taken on the line 22 of Fig. 1;

Fig. 3 is a perspective view of a portion of the door and vestibulejamb, the door being unlocked; and

Fig. 1 is a perspective View of a fragment of the door, showing in fulllines the locking dog in unlocked position, and showing in dotted linesthe locking dog in locked position. i

Similar reference characters refer to similar parts throughout theseveral views of the drawings.

On the rear of the door 1 are assembled suitable combination lockmechanisms, diagrammatically shownat 2 and 3, and a time lock mechanism,diagrammatically shown at 4. These look mechanisms are connectedtogether by a link 5, which in turn is connected by a link 6 to themiddle of a lever arm 7, which is pivoted at one end to the door, as at8, and which at its other end, as at 9, is pivoted to a locking lug 10.Looking lug 10 is suitably mounted and guided in the door, and itsfunction is to prevent or allow movement of a segment 11 from lookingposition to unlocking position. To this end, segment 11 is mounted onthe door for slidable movement across an end of lug 10 when lug 10 is inretracted or unlocked posi tion, and the arrangement being such that,when segment 11 is in locked position, lug

10 may be moved into locking position across an end of segment 11. Thiswill prevent movement of segment 11 into unlocked position until lug 10has been-retracted to allow segment 11 to move by. Segment 11 is movableinto and out of locking position from a handuvheel 12, which is at theoutside of the door, beingmounted on the end of a shaft 13, which isjournaled in the door, shaft 13 at its inner end having a pinion liwhich is constantly in mesh with teeth 15 provided on segment 11.Segment 11 also carries a locking dog 16, which extends outwardly and ispermanently engaged in a recess 17 provided therefor in one of theholding lugs 18, which constitute a part of a locking ring 19. Ring 19may be held .revolvably in place on the vestibule 20 by turning out arabbet 21 in the vestibule, and forming a retaining groove for the ring19 by securing circular box plates, such as 22, to the vestibule behindthe ring 19. WVhen locking ring 19 is moved to locked position, its lugs18 are moved into locking engagement behind cooperating lugs 23 providedon the door, and when looking ring 19 is moved into unlocked position,its locking lugs 18 align with recesses between the lugs 23 of the door,permitting the door to be opened. Suitable spring detents 24 may beprovided in the vestibule jamb to yieldingly maintain the locking ring19 in adjusted position. To permit movement of locking dog 16 into andout of locking position, the bolt-frame 25 of the door is suitablyslotted, as at 26.

In combination with the above, there may be provided a day-gate 27 and aglass frame 28 .of usual constructions. The vestibule jamb 20 may besecured to the wall 29 of thevault or safe by any suitable means, andabout the front of the vestibule there may be provided an architrave 30,and at the .rear of the frame there may be provided a flange bar 31.

The operation-of the door and locking mechanism will be apparent fromthe above description. When the locking lug 10 is in unlocking position,as shown in Fig. 1, the door may be locked and unlocked by merelyrotating the handle 12, on account of the connection between pinion 1 1with teeth 15 of segment .11, which in turn is in engagement withlocking ring 18 through locking dog 16 and recess 17. When segment 11has .or time lock been removed into locking position through operationof hand-wheel 12, movement of looking lug 10 into position across theend of the segment, by means of the combination mechanisms, will preventthe movement of segment 11 into unlocking position, either by means ofhand-wheel 12 or otherwise, and will thus prevent the unlocking of thedoor until locking lug 10 has been retracted by the combination and timelock mechanisms.

As many changes could be made in the above construction, and as manyvarious embodiments of this invention could be made without departingfrom the scope thereof, it is intended that all matter contained in theabove description or shown in the accompanying drawings be interpretedas il lustrative and not in a-limiting sense.
